Desiccant Breathers
Guardian Series
• Air Sentry® was the first to integrate check valve technology into a desiccant breather
• GUARDIAN™ takes check valve technology and cost-saving replacement measures to the next level.
• Air Sentry® also introduces four exclusive advancements that will again raise the bar in contamination control:
• Tritan® Construction - GUARDIAN™ is the first breather ever constructed of Tritan®. This patented material is the most chemical-, temperature-, and impact-resistant combination casing on the market.
• Isolation Check Valve - GUARDIAN™ is first again with an isolation check valve, which isolates the adsorbent from exhaust air to lengthen service life of the desiccant while also protecting it from volatile and splashing fluids.
• Integrated Compound Vacuum / Pressure Gauge - This proprietary feature is a true-life accurate indicator of filter conditions.
• Stackable - Stack cartridges to extend the life of breathers even further using the Modular Stack Ring™. This proprietary feature lengthens the service life, reducing cost and maintenance intervals.

Category List:
D-Series
• D-Series breathers feature numerous models in a variety of sizes, designed to satisfy the requirements of most stationary fluid management applications.
• All D-Series models feature 2-micron solid particle filtration and are available with airflow ratings of 20 cfm.
• The D-Series is constructed of industrial grade raw materials, tested to ensure a wide range of chemical compatibilities, and features high impact resistant ABS top and bottom caps.
• As with all Air Sentry breathers, the silica gel turns from gold to dark green to visually indicate the adsorption of moisture and confirm the breather is getting the job done!

Z-Series
• Z-Series breathers are designed for applications where space is limited or air flow requirements are below 10 cubic feet per minute (cfm).
• The Z-Series breather is typically used on gearbox applications and has been proven to work well on low fluid volume applications where mounting space is limited or where a larger breather won’t fit without remote mounting.

Category List:
XR-Series
• XR-Series breathers are designed for extreme environment applications where protection from dust, moisture and vibration are critical.
• XR-Series breathers include a metal reinforced base available with male NPT threads to adapt to your equipment. The base is designed to handle the rigors of high vibration applications.
• The top cap implements two check valves to prevent outside moisture and solid contaminants from entering the breather until there is a need for airflow.
• The XR-Series design allows for economical replacement of the desiccant cartridge.

R-Series
• R-Series breathers are suitable for high vibration applications including off-road vehicles, construction vehicles, haul trucks, and farm vehicles typically equipped with hydraulic fluid reservoirs.
• R-Series breathers are easily mounted in place of standard breather capsvia rugged steel pipe threads, included with all models except the R-111.
• The R-Series rebuildable design allows for economical replacement of the desiccant cartridge.

L-Series
• L-Series Air Sentry® In-Line Filter/Dryers remove water vapor and solid contaminants from air exhaust lines, low pressure compressed air lines, vacuum lines, and other in-line airflow applications where clean, dry air is required.
• Air enters the filter/dryer in one end and is cleaned and dried before leaving the other end. Solid particles are removed down to 2 microns.
• Activated carbon versions are ideal for removing undesirable fumes and odors from air or other gases being vented to the atmosphere.

Category List:
M-Series
• M-Series breathers are designed from heavy duty materials capable of handling the requirements of the most severe environments.
• They replace the standard breather cap or vent tube on tanks and reservoirs. Pipe threads on the bottom standpipe make the units easy to install.
• All M-Series designs have 2 micron pleated filters and silica gel bags that are easily replaced.
• The M-Series design features our proprietary Splash Sentry®. This device is included in all M-Series models and prevents foaming or splashing fluids from entering the breather during normal operating conditions.

X-Series
• X-Series breathers are the perfect solution for high humidity and high dust environments. To extend the desiccant’s life in these environments, the X-Series incorporates two check valves.
• The intake check valve allows airflow into the breather only when differential pressure between the atmosphere and reservoir exceeds a 0.3 psi threshold, while the exhaust check valve permits air to exit the reservoir when the differential pressure between the reservoir and atmosphere exceeds a 2.1 psi threshold, providing a closed system until air flow is required.
• The check valves extend the life of the desiccant by allowing the air to flow through the breather only when needed to protect the integrity of the tank..
• The X-Series rebuildable design allow for economical replacement of the desiccant cartridge.

Vapor Sentry
• Vapor Sentry Oil Coalescing Breather solves oil mist problems that form droplets on the outside of the equipment.
The original breather or vent cap is removed and replaced with the Vapor Sentry. The original breather is installed on top of the coalescing unit.
